Hello– I have this problem as well. In IE7 it says “error on page” when I click the “Add new page” link under “Additional pages”.
I think I’m up to date on everything I can think of; see my config info below.
If it matters, I have put my sitemap on the root, visible at fordfam (dot com), called “sitemap.xml”. My blog is at /matthew/blog. (Yep, down two levels from the root which I know is a bit unusual.)
Config:
WinXPSP2
IE7
Got latest java from Sun’s website and restarted browser
plugin 3.0b10
Also using UTW tag plugins
WP 2.2.2
I’d appreciate any help, as I want to use the plugin but still include my main site pages in it as well.
